Headlamp upgrade

Hi. I'm thinking of fitting the new Osram bulbs as my headlights seem p**s poor - either that or I need new driving glasses.

Can anyone recommend them as giving a better range of illumination or would i be wasting my heard earned. How easy are they to fit or is it a front of the car off job just to swap the bulbs?

Advice appreciated.

p.s I visited Autotechnica in Hull with a small problem on the car. Recommended and friendly too.
